Orion Health Rate Limits

Orion Health does not publish public per-second or per-minute rate-limit numbers for its FHIR, Population Health, HIE, or Rhapsody Integration APIs. Deployments are typically customer-managed (on-premises or customer cloud) or Orion-hosted with rate limits agreed in the underlying customer contract. Throughput on the Rhapsody integration engine is capacity-planned per deployment.

Orion Health Rate Limits is the machine-readable rate-limit profile for Orion Health on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring varies and messages_per_second.

The profile also includes 4 backoff/retry policies defined and response codes documented for unauthorized, forbidden, notFound, serverError, and serviceUnavailable.

Tagged areas include FHIR, Healthcare, HIE, Interoperability, and Rate Limiting.

Limits

FHIR API Throughput deployment
varies
bound by deployment sizing
Throughput is governed by the deployed Orion Health environment (Orion-hosted or customer-managed) rather than a public per-tenancy rate.
Population Health API Throughput deployment

bound by deployment sizing
HIE API Throughput deployment

bound by deployment sizing
Rhapsody Integration Throughput deployment
messages_per_second
bound by Rhapsody engine sizing
Rhapsody throughput is capacity-planned per engine deployment and depends on the configured routes, filters, and downstream destinations.

Policies

Capacity-Bound Throttling
Throughput limits are determined by the deployment sizing (Orion-hosted or customer-managed) rather than a public per-tenancy rate-limit table.
Backoff Strategy
Clients should implement exponential backoff with jitter on 5xx responses; honor any Retry-After header when present.
HL7 / FHIR Bulk Patterns
For large-population data exchange use FHIR Bulk Data ($export) or Rhapsody batch routes rather than transactional FHIR REST calls.
Customer Agreement
Specific rate-limit numbers, SLAs, and capacity commitments are defined in the underlying customer agreement and operations runbook for each deployment.
